Hi Jesus,

There is a tricky way to do a projection of a map in Chimera. You can use the map binning capability. For example, if map #0 has 144 planes along the z axis I can add all those planes with

vop bin #0 binsize 1,1,144

This can be done with a dialog instead of a command using Tools / Volume Data / Volume Filter, filter type bin and type in the bin size as 1 1 144.

You also want a view along an axis other than x, y or z it sounds like. To do that you would resample the map on a new rotated grid so that the z axis is along the desired projection axis. The following video shows how to use the Chimera volume dialog subregion selection capability to do that

Hi Jesus, Sorry, I don't think there is a way, currently. Here is the most recent information I could find on that topic:

Hi,

Is there a way to project a 3-D volume into a single 2-D image plane in Chimera?

For example, I want to load a volume twice into Chimera and view the two copies side by side in an identical orientation (manually set by rotating the volumes with the mouse). Then, I want to view one of them as a 2-D projection along the axis that comes out of the screen.

While a "solid" representation of the volume is similar, it is not exactly what I need...

Thanks!
